The present invention relates to looms and more particularly to the type in which the yarn is carried by spools mounted on tube frames which are carried by an endless feed ing mechanism to present the spools conse'cutively to the loom. An object of this invention is to make it possible to use a spool which is substantially the length of the tube frame notwithstanding the width of the material being woven. Another object of the invention is to provide a connection be tween the tube frame and the spool intermediate of the ends of the latter in order to permit the use of a single long spool. with wide loom tube frames withoutany danger I of the sagging of the spool between its ends.

, Still another object of the invention is to support on a tube frame.

Fig. 6 is a fragmentary view showing the sag connection between the tube frame and spool. p v In looms and particularly those of the type designed for weavingAxminst-er rugs and other pile fabrics, it is customary to mount the yarn which forms. the pile upon spools supported on tube frames which are presented to the loom consecutively by an endless carrier. Heretofore, when the material being wovenhas been of considerable width as in wide rugs, each tube frame has supported thereon a plurality of axially aligned spools extending across the entire width of the material being woven. The use of a plurality of spools for .a single wide tube frame has heretofore been considered necessary as the weight of the material would heretofore produce a sagging condition in a single long spool dueto the weight of the yarn and the pull of the yarn in weaving. This would cause an undesirable condition in the weaving operation.

According to this invention, itis possible to use a single long spool for each tube frame notwithstanding being woven as this sagging condition is entirely eliminated.

On

opposite ends of the tube 5; are fitted the flanges 7 madefrom sheet metal and pressed to; provide a central tubular portion 8 fitting and a surrounding periphery .9 which may, be. engaged by a spring brake finger l'Osupported by the-tube framelpu The sag preventionconnection between the tubeframe and the spool, ,in this instance, is arranged between the and comprises preferably a. surrounding flange .llonthe tubular portionfi substantially midway betweentheend flanges '7. This flange has a cylindrical outer surface 12 forming a hearing; or shoulder for cooperating with a bearing on thetube frame I. In this, instance, the bearing on the tube frame comprises a housing 13 havin itsupper surface conforming to the surface of the cylindrical surface 12 and provided with. roller bearings lltO reduce the friction be. tween the two bearingmi This cooperation betweeirtlie rollers ljandthe. surface 12 prevents the saggingof thespool toward the tube frame when the spool; and the tube frame are situated; on the underside of the endless carrier. i a
